psreit,
I know several children personally that didn't READ until 10 or 11, one of them was 12. Guess what? They are just fine now and are at "grade level".

You would never know that they couldn't read until that age.
I know one girl that struggled and struggled and I tried to convince her mother that she just wasn't ready, but she was nervous so she put her in school. She got special attention and a "reading specialist" for the year and she didn't improve for a long time. Finally, the next year, after 1/2 of a school year she "got it". Guess what the specialist told her mother? "It seems she was just not ready before and she just needed to grow a little bit." Surprise!
And about the counting money, it will come.

In the grand scheme of things, 8 is still pretty young.
You are doing fantastic!! Don't worry.
Nancy
